WATER-MOTOR.

SPECIFICATION forming part of Letters Patent No. 559,740, dated May 5,1896.

Application filed August 4, 1892. Serial No. 442,188. (No modehl To allwho? it may concern:

Be it known that I, ALLEND. MOORE, a citizen of the United States,residing at Montpelier, in the county of W'ashington and State of.Vermont, have invented a new and useful Improvement in \Vatenlrlotors,of which the following is a specification, reference being had. to theaccompanying drawings, representing a water-motor embodying myinvention, in which- Figure 1 represents a perspective view of themotor. Fig. 2' is a central vertical sectional view through theinclosing case. Fig. 3 is a central sectional view of the tube formingthe water-chamber and of the oscillating valve-cylinder inclosedtherein. Fig. l represents the water-motor, with the inclosing caseshown in transverse sectional view, in a vertical plane passing throughthe center of the case on line 4; 4, Fig. 2. Fig. 5 isa transversesectional view of the inclosing case on a horizontal plane passingcentrally through the case and through the tubes forming thewater-chainbers on the line 5 5, Fig. :2. Fig. 6 is a view of the tubeforming the waterchamber. Fig. 7 represents the oscillating cylinderforming one of the valves. Fig. 8 represents a portion of avalve-cylinder with its inclosing tube with the port open. Fig. 9 is aview of the same with the port nearly closed. Fig. 10 shows a portion ofthe revolving bucket wheel with two of its buckets shown in perspectiveview. Fig. 11 is a top view of one of the buckets, and Fig. 12 is asectional view of the bucket on the line 12 12, Fig. 11.

Similar letters refer to similar parts in the difierent figures.

My invention relates to certain improvements in water-motors, having forits object to increase the simplicity, durability, and efficiency of themachine, and consisting in the I construction and arrangement of theseveral parts, as hereinafter described, and set forth in the annexedclaim.

Referring to the accompanying drawings,

.A denotes the inclosing shell or case within attached to the shaft 0,and provided at its periphery with a series of buckets B Preferablyformed integrally with the disk B are a series of equidistant shallowcups pro jectin g radially fromv the periphery of the disk. Between eachbucket and the next adjacent bucket the disk 13 is made thicker, forminga triangular rib 13*, having curved sides B and a sharp edge 13. Thebase of the triangular rib B extends radially the entire length of thebucket B while the opposite end extends within the shallow cup formingthe next bucket.

The wheel 13 revolves in the center of the shell A, and streams of waterare directed tangentially against the buckets upon opposite sides of thewheel through the ports E in the tubes E, held in and extendingtransversely through the shell A. These tubes E form water-chambers,from which water under pressure is admitted through the ports E to therotating wheel B, and these tubes are preferably connected with a commonfeedpipe E communicating with the water-main. The valves by which theports E are opened and closed consist of oscillating cylinders F,filling the tubes E and provided with openings F, which are made tocorrespond with the ports E by the angular motion of the cylinders F.The cylinders F are open at one end to admit water and are provided atthe opposite end with a head or disk F provided with holes F to preserveequal water-pressure and attached to a spindle F extending through astuffing-box F through the shell A to receive a radial arm The radialarms F attached to the spindles F upon opposite sides of the shell, areconnected by a rod F to secure the simultaneous rocking motion of thetwo cylinders F by means of a hand-lever G, pivoted at the side of ashell A and operatively connected with the connecting-rod F. The ports Ein the tubes E and the openings F in the cylinders F are madepf the samesize and oval in form, with the narrow extremity of the opening F placedopposite the narrow extremity of the corresponding port E, so the narrowextremities of the opening and port will be brought together in theoperation of closing the port, causing the port to be contractedlaterally as it is closed by the angular movement of the cylinder tomaintain a solid and round stream up to the last moment of closing. Thehead I is provided with holes F to admit water to the-space F in orderto equalize the water-pressure upon both sides of the head, and thecylinder F is provided with an opening E, diametrically opposite theopening F, to allow the water-pressure of the stream of water passingthrough the port when the port is open and to counteract the pressure ofwater acting through the opening F against the inner side of the tube Ewhen the port is closed.

The tubes E are held in screw-threaded collars II II, provided withflanges H H, which overlap the sides of theshell A, making a tightjoint, the construction allowing the tubes E to be rocked, so as to varythe direction of the stream relatively to the rotating bucket-wheel B,so the angle at which the streams of water shall impinge against thebuckets can be adjusted.

The stream of water striking against the edge of the wheel, eitherdirectly from the ports or as deflected from the buckets, is receivedupon the acute edges B and deflected laterally away from the wheel, soit will not offer any resistance to the rotation of the wheel, and thetriangular rib 13" being thicker than the disk B the current of waterpassing the rib is carried out of contact with the sides of therevolving disk.

The form and arrangement of bucket-s are shown in Figs. 1O, 11, and 12.The lateral sides a a of each bucket are slightly flaring and the rearside 1) is more flaring, forming an angle with the bottom of the bucketof preferably sixty or seventy degrees.

The front side of the bucket is cut away at c, and the bottom d of thebucket lies in a radial plane. This form of bucket I believe to be new,and it possesses the advantage of allowing the water to be so deflectedfrom the surface of the bucket into the space between the inclosingshell and the revolving bucketwheel that it will not be brought intocontact with the streams issuing from the ports, and will also becarried entirely out of the path of the buckets, in order that the forceof the water as deflected from the surface of the bucket shall not offerany resistance either to the revolving bucket-wheel or to the streams ofwater emerging from the ports.

The wheel B is carried upon the inner end of the shaft 0 and is providedwith hubs B of equal length, which permits the bucketwheel to beattached to the shaft in the position shown in the accompanyingdrawings, or turned end for end, when it is desired to'reverse itsmotion. WVhen so turned to run in the opposite direction, the tubes Eare turned in the shell A to throw the streams of water in the oppositedirection from that shown in the drawings, and the oscillatingvalve-cylinders F are adjusted to correspond with the changed positionof the tubes E.

In order to open or close the valves, an angular movement is given tothe hand-lever G, causing the valve-cylinders F to be simultaneouslyrocked within the tubes E by 7 means of the connecting-rod F and radialarms F and the hand-lever is locked in position by a pin passing throughthe lever and one of the holes in the curved rail 6, or by any of thewell-known methods for accomplishing the purpose. The periphery of thecase A is curved concentrically at I I with the tubes E in order toprovide a space I 1 between the case and the tubes to allow the water toflow downward freely and be delivered from the case through the hopperJ.

The hopper J is fitted within the case Aby bringing its upper and largerend against the projecting shoulder J and filling the acute corner at J2 between the hopper and case with molten lead. The hopper J iscontracted at its lower end so the water can be discharged from the caseA through the hopper into the mouth of a sewer or drain-pipe.

What I claim as my invention, and desire to secure by Letters Patent, is

In the water-motor, the combination of a case A, bucket-wheel B inclosedin said case, tubes E, E, held transversely in said case and uponopposite sides of said bucket-wheel, said tubes being capable of radialadjustment in said case, a common feed-pipe E communicating with saidtransverse tubes, whereby a common water-pressure is maintained in eachof said tubes, concentric oscillating valves held in said tubes, saidtubes having openings which are opened and closed by said valves, andsaid valves being operatively connected so as to move synchronously,substantially as described.
